Figure 3. (a) Fabrication of Cu3(PO4)2@magnetite thin film (Cu@MF) and Cu3(PO4)2@magnetite nanoflower (Cu@MNF) in a biphasic system of toluene and phosphate buffer saline (PBS) in a hemispherical base quartz tube, 20 mm OD, 17.5 mm ID. (i) Schematic for the creation of Cu@M composites in a VFD. Oleic acid-coated magnetite nanoparticles were disseminated in the toluene phase with all experiments using a 1:1 mixture of toluene and PBS, with CuSO4 then added quickly, followed by VFD processing at 7500 rpm. (ii) SEM of Cu@MF formed at the toluene/PBS interface, while Cu@MFN present in the PBS phase. (b) The reaction of 2-acetamido-3,4,6-tri-O-acetyl-α-d-glucopyranosyl chloride with 4-nitrophenol in the absence of a phase transfer catalyst in an aqueous sodium hydroxide solution and dichloromethane, with the yield of the product plotted as a function of tilt angle and rotational speed of a quartz tube, for either a flat or hemispherical base14.
